H125 Micro Quad V1 -7mm/8.5mm Micro SciSky Based (under $50)

Looking for an affordable trainer quad that you’ll still enjoy flying after you’ve mastered your moves? This H125 micro quad might be the right choice. Measuring just under 100mm long, about 75mm wide, and 125mm diagonally, this is the perfect medium-sized micro quad for just about every skill level and every age. Weighing in at just 45 grams fully-stuffed, including the battery! We’ve based this micro around the 7mm brushed motor because we’ve found that they’re inexpensive yet get the job done. Instead of using screws and aluminum spacers, the quad is designed around a peg system that saves a significant amount of weight and makes construction and repairs a snap. Using a Turnigy nanotech 260mah lipo, you will get about 4 1/2 minutes of flight time. If you want to see this quad fly check out our micro quad flight video.
